101 years ago a huge explosion occured over Tunguska, the blast causing devastation over 2,000 square kilometers and destroying 80 million trees with a force greater than that of 1,000 nuclear bombs.
The Tunguska Explosion, presumably caused by a comet, is the greatest space catastrophe humankind has ever witnessed. Even a century later, the Siberian blast still attracts scientists who hope to unveil its mystery.
